Definitions
- the invention relates to a method of cleaning the outer surface of a cylinder in an offset printing press, such as a blanket cylinder, an impression cylinder, a plate cylinder, or an inking cylinder. More particularly, the invention relates to a method of cleaning the outer surface of a cylinder by using a cleaning fabric intermittently or continuously fed from a supply, and engaged with and pressed against the outer surface of the cylinder.
- the device comprises an expandable pad opposed to the outer surface of the cylinder and mounted on a frame.
- a cleaning fabric is directed to a take-up roll from a supply roll through the pad.
- the take-up roll is intermittently rotated to take up the cleaning fabric so that the cleaning fabric is intermittently fed to the pad from the supply roll.
- the cleaning fabric is intermittently engaged with and pressed against the outer surface of the cylinder by the pad which is inflated by air under pressure whenever the cleaning fabric is intermittently fed, to clean the outer surface of the cylinder.
- the cleaning fabric is nipped between the pad and the cylinder within a stripe range having a nip width in the feeding direction of the cleaning fabric.
- the cleaning fabric is engaged with the outer surface of the cylinder for a constant period of time, throughout a cleaning cycle for accomplishing the cleaning of a cylinder.
- the cleaning fabric is fed for a length a time which corresponds to the nip width of the cleaning fabric, throughout the cleaning cycle.
- the cleaning fabric is nipped between the pad and the cylinder within a stripe range having a nip width of about 5 to 8 mm.
- the cleaning fabric is fed for a length of about 5 to 8 mm every three rotations of the cylinder.
- the cleaning fabric is fed twenty times in the cleaning cycle so that it consumes the cleaning fabric of about 100 to 160mm.
- the used fabric is then taken up about the take-up roll for disposal.
- the cylinder is made clean more and more in accordance with the progress of cleaning toward the end of the cleaning cycle. Accordingly, the cleaning fabric is made heavily dirty and saturated with dirt only at the beginning of the cleaning cycle. The cleaning fabric gradually decreases in degree of the dirt in accordance with the progress of cleaning toward the end of the cleaning cycle. As to the latter half in length of the cleaning fabric used in the cleaning cycle, it is little dirty and still available to clean the outer surface of the cylinder. Accordingly, it is wasteful of cleaning fabric to dispose it in spite of the availability thereof.

- Fig. 1 illustrates a device for cleaning the outer surface of a cylinder 2 by a method according to the invention.
- the device comprises a pad means 4 opposed to the outer surface of the cylinder 2 and mounted on a frame 6, as shown in Fig. 3.
- a cleaning fabric 8 is directed to a take-up roll 10 from a supply roll 12 through the pad means 4.
- the take-up roll 10 includes a shaft 14 on which an arm 16 is mounted through a one-way clutch, as shown in Fig. 2.
- the arm 16 is pushed and swingingly moved by a rod 18 in an air or hydraulic cylinder 20 and then returned by a spring 22 about the shaft 14 so that the take-up roll 10 and the shaft 14 are intermittently rotated in one direction by the one-way clutch to take up the cleaning fabric 8 whenever the arm 16 is swingingly moved by the rod 18. Accordingly, the cleaning fabric 8 is intermittently fed to the pad means 4 from the supply roll 12.
- the arm 16 includes a cam surface 24 which is adapted to be engaged with a stop bar 26 mounted on a lever 28 to restrict the movement of the arm 16.
- the stop bar 26 includes a roller 30 which is engaged with the outer surface of the take-up roll 10 by a spring 32 connected to the lever 28. Accordingly, the lever 28 is swingingly moved integrally with the stop bar 26 and the roller 30 in accordance with the increase in diameter of the take-up roll 10 so that the stop bar 26 and the cam surface 24 cooperate with each other to keep the length of the cleaning fabric 8 fed a time substantially the same regardless of the increase in diameter of the take-up roll 10.
- the cleaning fabric 8 is intermittently engaged with and pressed against the outer surface of the cylinder 2 by the pad means 4 whenever the cleaning fabric 8 is intermittently fed, to clean the outer surface of the cylinder 2.
- the pad means 4 may comprise an elastic rectangular or round pad.
- the frame 6 is moved toward the cylinder 2 by drive means such as air or hydraulic cylinder so that the cleaning fabric 8 is intermittently engaged with and pressed against the outer surface of the cylinder 2.
- the pad means 4 may comprise an expandable pad as disclosed in U.S. Patent No. 4,344,361.
- the cleaning fabric 8 is nipped between the pad means 4 and the cylinder 2 within a stripe range having a nip width W in the feeding direction of the cleaning fabric 8.
- the device is arranged to accomplish the cleaning of a cylinder 2 in a cleaning cycle.
- the cylinder 2 is made clean more and more in accordance with the progress of cleaning toward the end of the cleaning cycle.
- the method comprises the step of predetermining periods P for each of which the cleaning fabric 8 is engaged with the outer surface of the cylinder 2 a time so that at least some of the periods P1, P2, ---- Pn are different in length from other periods in the cleaning cycle C1, as shown in Fig. 7.
- the cleaning fabric 8 may have a cleaning agent or detergent previously impregnated thereinto, as disclosed in U.S. Patent No. 5,368,157.
- the cleaning fabric 8 may have a cleaning agent or detergent in the form of jelly or paste applied onto the cleaning fabric 8.
- a cleaning agent or detergent may be received in a receptacle which is mounted on the printing press so that the cleaning fabric 8 is directed into the receptacle from the supply roll 12 and then fed to the pad means 4.
- the cleaning agent or detergent is impregnated into the cleaning fabric 8 when the cleaning fabric 8 is directed into the receptacle.
- the cleaning agent or detergent may be sprayed onto and impregnated into the cleaning fabric by nozzles mounted on the printing press, as disclosed in U.S. Patent No. 4,3144,361. In the cases, the method can eliminate the waste of not only cleaning fabric 8 but also cleaning agent or detergent.
- the method further comprises the step of feeding the cleaning fabric 8 for a length L1 a time which is less than the nip width W of the cleaning fabric 8, as shown in Fig. 6.
- the periods P1, P2, ---- Pn are gradually lengthened in accordance with the progress of cleaning from start to end of the cleaning cycle C1. Accordingly, in comparison with the prior art shown in Fig. 4, the cleaning fabric 8 is made considerably dirty throughout the cleaning cycle C1, as shown in Fig. 5.
- Numbers 1 to 6 in Fig. 4 and Fig. 5 represent the degree of dirt of the cleaning fabric 8. This decreases the total of lengths L0 of the cleaning fabric 8 used in one cleaning cycle C1 and eliminates the waste of cleaning fabric 8 and cleaning-agent or detergent.
- the air or hydraulic cylinder 20 is merely required to feed the cleaning fabric 8 for a short length L1 a time.
- the air or hydraulic cylinder 20 can therefore be considerably miniaturized.
- the cleaning fabric 8 can be intermittently and forcibly fed even when nipped between the pad means 4 and the cylinder 2.
- the number of times of feeding the cleaning fabric 8 per second or minute is gradually decreased in accordance with the progress of cleaning from start to end of the cleaning cycle C1.
- the number of times of feeding the cleaning fabric 8 per second or minute can be conveniently increased at the first stage of the cleaning cycle C1 to supply enough cleaning agent or detergent to effectively clean the outer surface of the cylinder 2, without the waste of cleaning agent or detergent. This can save time for cleaning the outer surface of a cylinder 2.
- the periods P are divided into a plurality of groups C1 to G6 and gradually lengthened group by group from start to end of the cleaning cycle C1, as shown in Fig. 8. Accordingly, the number of times of feeding the cleaning fabric 8 per second or minute is gradually decreased group by group from start to end of the cleaning cycle C1.
- relatively shorter periods P1 are applied to a portion or the whole of the substantially first half in length of the cleaning fabric 8 used in the cleaning cycle C1, as shown in Fig. 9.
- Relatively longer periods P2 are applied to the residual of the cleaning fabric 8 used in the cleaning cycle C1.
- the method comprises the step of predetermining the feeding speed V of the cleaning fabric 8 engaged with the outer surface of the cylinder 2 so that the feeding speed V is gradually changed in a cleaning fabric, as shown in Fig. 10.
- the feeding speed V is continuously changed in accordance with the progress of cleaning from start to end of the cleaning cycle C1 and continuously lowered at least in a portion of the cleaning cycle C1. Accordingly, the cleaning fabric 8 is made considerably dirty throughout the cleaning cycle C1. This decreases the length of the cleaning fabric 8 used in one cleaning cycle C1 and eliminates the waste of cleaning fabric 8 and cleaning agent or detergent.
- the feeding speed V may be linearly lowered as shown by V1.
- the feeding speed V may be parabolically lowered as shown by V2.
- the feeding speed V may be temporarily increased at the middle of the cleaning cycle C1 and then lowered.
- the feeding speed V may be changed step by step in accordance with the progress of cleaning from start to end of the cleaning cycle C1 and lowered step by step at least in a portion of the cleaning cycle C1 as shown in Fig. 11.
- the feeding speed V may be lowered step by step along a straight line S as shown by V1.
- the feeding speed V may be lowered step by step along a parabola P as shown by V2.
- the feeding speed V may be temporarily increased at the middle of the cleaning cycle C1 and then lowered.
- the feeding speed V may be lowered with a plurality of gradients which are increased in accordance with the progress of cleaning from start to end of the cleaning cycle C1, as shown in Fig. 12.
- the feeding speed V may be firstly lowered with a gentle gradient as shown by V1 and then lowered with a steep gradient as shown by V2.
- the feeding speed V may be increased with respect to a portion or the whole of the substantially first half in length of the cleaning fabric 8 used in the cleaning cycle C1 and lowered with respect to the residual of the cleaning fabric 8 used in the cleaning cycle C1, as shown in Fig. 13.
- the feeding speed V may be high with respect to a portion or the whole of the substantially first half in length of the cleaning fabric 8 used in the cleaning cycle C1 and then changed to be low as shown by V1.
- the -feeding speed V may be lowered step by step as shown by V2 or continuously lowered as shown by V3.
